Curious as to what everyone has run with stock 400s and 440s when I say stock I mean stock. maybe a different carb and set of headers at the most... Il start out by saying a buddy of mine had a 64 dodge that had a 440 straight from a New Yorker all he did was spray paint it and put a 750 Holley on the cast intake and a set of headers with 3:23 gears the car would run 13:20s all day

My stock 77 Dodge truck ran 15.7 it would be a little better had 31inch tires and 323gears.

I believe that because the New Yorker and other C-body cars had some stout cammed 440's and 400's from the factory to pull all that weight. In a lighter car it was a different animal.
My friends bone stock 67' New Yorker was running high 15's and it weighed 4000 +

67 dodge stock 67 long block small cam headers intake 800 Holley through the mufflers on street tires with 3.23 gear runs 12:85 best .. That's at 3900 with me in it ..

Lots of different compression ratios between the two engines throughout the years. Heads too.

On a 9.5:1 440 with mild cam, headers and 750 Holley, I ran 104mph at 3,640 lbs. with 3.23 gears. Stock cast iron intake and 452 heads!

High 12's low 13' with a freshened stock 440 under 4000 lbs. is pretty easy.

Have a bone stock '77 440 out of a 1 Ton Van in my Charger.
Low compression, stock intake, original thermoquad, HP manifolds, 2 1/2" TTi exhaust, 3.23 Sure grip

Went 14.91 @ 90+ mph, no idea what it weighs or weather conditions

Article I read somewhere, factory performance claim for a '71 4 BBL 440 Charger ran 14.50

STOCK 72 Duster. late model smogger 440, untouched from the boneyard.

67 915 heads, stock. 67 stock iron intake.

Thermoquad

Stock, stock, stock.

Oh it did have 1 7/8 fenderwell headers and exhaust to the rear end.

3.23 gears, with a 255 Dunlop Qualifer.

Newly built ran 13.60's @ 103. Working on the tune up, front and rear suspension, adding frame connectors, etc...got it to 13.30's.

I miss that car..

Stock 440 in my 72. Well it did have some 2295s in it, but I didnt find till much later they were in it. Motor was worn beyond belief. Didnt have squat for compression. 2 lbs of OP at idle when hot.

CH4B intake, 750 Eddy untouched, small tube headers. 3.23s. Ran 14.01 @ 98.46 on basic radial tires. Had to walk it out of the hole.

back in the 80s early 90s I had a 76 Newport with a 400. The car didn't have cats on it. I worked the thermoquad and it ran right with the stock mustangs and monte carlo ss. I took it to the track a few times and I'm thinking it ran very low 15s. Most fun car I ever had

69 Coronet - 3600lbs with me
magnum 383 with 750 Holley and headers, 3.91's 14.30
same car but torker+2" spacer, no ps, 7" slicks, 3000 stall 13.20
how I tried to get 12.99 out of that!

69 Charger, also around 3600lbs laden IIRC
stock 440 with 750 vac sec and headers, 3.23's 14.02 IIRC
That car was no quicker with 4.10's with the stock cam and such

70 Sport Fury 4200lbs
the same
magnum 383 with 750 Holley and headers, 3.91's
as the Coronet had earlier 14.12 leaving off idle on 225/75/15's. That was a mine shaft day and it was never close to that time again =)

I love these types of threads, 13.20s in your buddies Dodge was cooking

Hearing some good stuff here love to hear what a stock low buck BB mopar can do...

A few more I know of at the local dragstrip is a guy with a 66 coronet has a 400 in it guy drives it to the track and claims it's stock low mile from a cordoba nothing but headers and a aluminum intake and Holley it runs 14:80s -14.90s

Another guy has a 63 plymouth fury says it's the original 383 all stock just a re ring and a 284 484 mopar cam with a edlebrick intake and a 750 dp headers and 3:91 gear the car runs very low 13s and he says hes hit high 12:90s in good air

A buddy who is a member has a 68 Sat with basically a stock 440. Idk what year of motor. No compression to speak of, I do know that. Does have a 292 Comp cam. 750 DP. Headers. 3.23s I think he went 12.20s or 30s.

1974 newport 2dr. 4880lbs. stone stock 400 with Bbody hipo exhaust manifolds with 2 1/2" pipes through shorty, cheapo turbo mufflers. super tuned thermoquad and distributor re-curve. 50lbs. in front tires [Hr70x15 i think], 25"tall G60 mcCreary dirt tires on rear mounted on 8"wide [rusty]chrome steel slot wheels at ???lbs.[i forget] pressure. rear gear was factory 9 1/4" with 2.7-2.9[???] what ever it was. 15.95[best]-16.50 at beaver springs. i can't remember the mph. that barge was the best running of the bunch of 74-78 Cbody tanks my brother and i ran for winter beaters in the early 80's to early 90's. i kept that engine and transmission when that car was finally junked due to rust. that 400 would flat out run ! i don't know anything about the engine internals, or if it was re-built at one time or not. was expecting mid 17-low 18second et's. dark brown with a gaggy mustard yellow interior. a beauty she was not.

1966 New Yorker 440 TNT; dual ex., dual snorkel air cleaner, 3.23 gears, no suregrip, stock tires, best of 15.66 at 92 MPH.

Lot of fun on the street!!

1973 Charger rally. 400 Magnum. Bought it running like crap. Had 3 burnt exh valves. Had a set of stock 906 heads with zero porting and a fresh valve job so I put them on it. Recurved the distributor and tuned on the Thermobog carb. Stock exh manifolds and air cleaner. 14.90 best ET. Did have a rebuilt 727 with a factory high stall 318 tq converter. 8 3/4 rear with 3.23 gears. I had several people warning me 360s and 400s were junk and to avoid them. One of the biggest Mopar myths.

Were factory tolerances that sloppy that ETs are that far apart? One B body ran low 13s while another ran mid 15s? Surely a Couple points of compression aren't worth 2.5 seconds

Could be. Mopar tolerance on all assemblies could be give or take 1/2 of an inch!

Also consider the diff in drivers...race ready weights, weather, track conditions, etc. It's totally apples and oranges.

True,now they are the two most sought after for stroker builds!
